Here's a quick tip if your having trouble with an embed flash player rendering over content that you want shown in your web page. You need to set the wmode variable to "transparent" Here's an example with a embed youtube player.

<object width="560" height="349" 
classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" 
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0">
<param name="allowFullScreen" value="true" />
<param name="allowscriptaccess" value="always" />
<param name="src" value="http://www.youtube.com/v/QPyVwPO3h4U?version=3&amp;hl=en_US&amp;rel=0" />
<param name="allowfullscreen" value="true" />
<embed width="560" height="349" type="application/x-shockwave-flash" 
src="http://www.youtube.com/v/QPyVwPO3h4U?version=3&amp;hl=en_US&amp;rel=0" 
allowFullScreen="true" allowscriptaccess="always" allowfullscreen="true" 
wmode="transparent" /></object>
